Egypt is a land of pyramids that stand magnificent and tall against the sky. Millions of people visit that country each year to see these fantastic structures. It was believed by the ancient Egyptians that man’s regulated and ordered life does not end on Earth, but continues even after his death. They also believed that their kings descended from the gods, and after death, they proceeded to join them in the other world. Many customs began to be followed in Egypt, and the most common was that the king during his reign would make a magnificent tomb in which he could be buried after death. These tombs were in the shape of pyramids. Their construction required enormous quantities of stones, manpower and took a long time to build. Similar monuments were found in South America too. Presently, about 80 pyramids still stand in Egypt; the most famous of which are the three at Giza near Cairo. The largest of the three is the pyramid of Pharaoh Cheops. These pyramids were built between 2690 B.C. and 2500 B.C., as estimated by archaeologists. It took a long time for ancient Egyptians to develop the art of building pyramids. Stones were transported across the Nile from quarries on the eastern bank. The base of the pyramids was nearly a perfect square. An immense amount of slave labour was employed to construct the vast structures. Stonecutters and masons used saws up to ten feet long. The burial chamber was so designed and located so that thieves would find it extremely to difficult locate and steal the vast treasure that was buried with the dead king’s mummified body. The three famous pyramids of Egypt are the pyramids of Mycerinus, Cheops and Chephren. They are 215 feet, 481 feet and 471 feet high respectively. One side of the base of Cheops’ Pyramid is 756 feet and it covers an area of 13 acres. The number of stone blocks used in its construction was 2,300,000. A permanent work force of 4000 was required for 30 years to build the pyramid.
